The project N-PERM aims at advancing our understanding on nitrous oxide (N2O) dynamics and budget in permafrost regions including Arctic and Alpine soils. We will achieve this goal by establishing continuous and long term N2O flux measurements at a permafrost-peatland, by using process-based models to simulate N2O fluxes and estimate future responses of Arctic ecosystem to climate change. Additionally, we will apply machine learning tools to the new and comprehensive datasets to deliver annual N2O budgets, upscaled to the northern permafrost regions. The work will improve our knowledge on permafrost climate feedbacks under present and warmer climatic conditions and helps to clarify the role of northern permafrost regions in the global N cycle in present and future.
